Farrah Abraham's highly-anticipated sex tape (entitled "Farrah Abraham: Backdoor Teen Mom," how original) was officially released by Vivid on Monday, May 16. Online searches for the "Teen Mom porno" and "leaked uncensored photos" have since skyrocketed... but 21-year-old Abraham claims that she doesn't plan on taking part in any of it. Meanwhile, fellow MTV reality star Cateylnn Lowell recently hit up Twitter to diss Abraham's porn star techniques... well, sort of. Read on for all the racy details!

Rumors started swirling on the web that Abraham had filmed an explicit sex tape last month - and the former "Teen Mom" star had no issue with immediately confirming those rumors. Reports also confirm that the popular porn company Vivid just bought rights to the film for a high, six-figured price (close to $1 million).Vivid founder Steve Hirsch released in a recent statment: "I'm happy to confirm that we have purchased it. We went after this movie as vigorously as any sex tape we've ever pursued... We felt it was definitely worth it, not only because of Farrah's popularity, but because the footage itself is amazing."

Apparently, Abraham hopes that the raunchy sex tape will help to revitalize her career - very a la Kim Kardashian. In fact, Hirsch said that Abraham even reminds him of a younger Kim K:

"I think many fans will be shocked at how truly explicit it is. Farrah is gorgeous, sexy, and absolutely uninhibited. Farrah's looks remind me of a young Kim Kardashian and we all know how her story turned out."

Hmmm...

Anyway, TMZgot hold of some of the naughty on-set porn photos... they feature (a barely clothed, sometimes naked) Abraham, lounging seductively on a bed, washing up in a bubbly shower, taking off her top to expose her ta-tas, and getting down-and-dirty with co-star James Deen. Here's one tamed image from the leaked photo collection...

One "Teen Mom" star who DID apparently watch the raunchy flick... Catelynn Lowell:

@CatelynnLowell: "All I have to say Is she sounds like a dying horse!! U kno who I'm talking about."

Yeah, I think we do... still no response from Abraham.

According to the adult entertainment company Vivid, the video is "shockingly explicit" and "[Abraham] takes James Deen as you'd never imagine, in a backdoor scene you'll never forget. With her tight young body and totally uninhibited sexuality, it's no wonder why she wanted to capture this moment in time. And now you can too!"

So... who curious to see Abraham's performance in "Backdoor Teen Mom?"
